Using Interactive Workspaces for Team Design Project Meetings

Abstract: An Interactive Collaboration Laboratory (ICL) has been established at the University of New Brunswick (UNB) to research the application of interactive information and communication environments for the architectural, engineering, and construction (AEC) industry. This paper provides a quick overview of the laboratory within the wider context of interactive collaborative workspaces. It identifies opportunities to enhance information communication, and group decision-making offered by the laboratory, and focuses on lessons learned to date from its use. The paper reports on a survey conducted among final year undergraduate students who used the environment over the course of three months for their senior design project meetings. A questionnaire was distributed to those students to investigate the impact of the environment upon the effectiveness of their meetings and decisions, the issues and processes where the environment was more (or less) useful, and the context within which the environment and tools were used. The questionnaire also investigated the impact of the environment and its tools upon their project, the quality of their work, and their overall satisfaction. Students found the laboratory to be specifically useful at the preliminary design stage when designing, viewing, and analyzing the site and building layouts of their projects, and determining the projectís sustainability requirements, and targets. The laboratory enabled student groups to view information from different perspectives, access remote information, and save captured information instantaneously. It also enabled them to collaborate more effectively, make more educated decisions, make better use of their time, produce higher quality work, and develop among them a relationship of trust, respect and mutual understanding. Investigating how best to use the labís technology to serve their needs, occasionally slowed down their progress and distracted them at times from focusing on their work.

Examining Complex Systems and Agent-Based Modeling for Improving Decision Makings in Construction Organizations

Abstract: The management on construction projects and organizations is very important. However it is poorly understood considering the declining performance of construction industry. Managing and predicting the work performance of a construction organization tends to be extremely difficult using conventional management approaches. This paper regards construction as a complex system and proposes the use of Agent-Based Modeling (ABM) as a management enhancement tool for construction organizations. Building on an organizational simulation platform proposed by the authors (Virtual Organizational Imitation for Construction Enterprises, VOICE), the influence of human and organizational factors on work performance has been investigated. Additionally, different management scenarios of a case study in construction bidding have been examined using a complete management cycle, Plan-Simulation-Check-Action (PSCA). The results indicated the new management tool can easily help decision makers to streamline processes, manage human resources, and testify any changes at real time. It demonstrated better practicability than conventional management. This paper highlighted the value of the proposed approach on managing construction organizations.

Manipulating IFC model data in conjunction with CAD

Abstract: The IFC model is used as a means of information exchange between AEC software applications. Currently, workflow aspects based upon IFC models still reside in a gray area between applications. This paper reports ongoing research work on a new approach that uses an online dynamic continually updated construction product data source for IFC based Building Information Models (BIMs). It focuses on different algorithms for parsing, interpreting and writing STEP ISO 10303 P-21 files. In between these stages various instantiation, deletion and updating process on the IFC model take place. The paper also investigates the ability of current software applications to work on the IFC model in a sequential order and points out some workflow management problems that were encountered during this process.

Using Business Process Management in Design Coordination for Construction Projects

Abstract: Engineering management plays a very important role in the economics of most developing countries. Nowadays, management is very common to all projects, while each design project has additional and unique set of design tasks. Project design failure occurs when one party (or parties) of the project team is/are unable to perform his/their contractual duties in presence of the project miss-coordination. In many cases, following a well-design management plan is a good attitude, compared to waiting for problems to occur and then try to react in order to avoid failure. Business project management has been proposed as a solution to provide insight into potential problem areas and to identify, address and eliminate them before they derail the project. The business process management interference in the design life cycle of a project is not to avoid all cases of miss-coordination and client requirements implementation (which are impossible) but to reorganize and manage them. The objectives of this research are: i) identify the main departments and their tasks, which can affect the project design life cycle generally for buildings and consequently the success or failure of the project coordination, ii) indicate the relative importance of every stage, iii) gather the activities affecting project management, iv) establishing a computer program in order to assist in project coordination, and v) develop practical recommendations and guidelines to avoid or decrease the effect of miss-coordination in design process. A detailed case study is presented to demonstrate the practical use of the proposed business process tool.
